Watch Coldplay's hilarious Game of Thrones musical featuring the cast!

Forget the tens of millions of album sales, headlining Glastonbury twice or the countless awards, Coldplay’s career has reached its peak with their incredible Game of Thrones musical sketch!

The spoof 12-minute documentary was filmed for the American Red Nose Day last night and is narrated by the dulcet tones of Liam Neeson throughout.

It opens with Chris Martin and Will Champion clumsily try and come up with some lyrics for the Game of Thrones tune before later unleashing their gem of a track ‘Rastafarian Targaryen.’

Some of the biggest cast members appear throughout the Band Aid-esque feature including Kit Harrington (Jon Snow), Emilia Clarke (Daenerys Targaryen), Nikolaj Coster-Waldau (Jaime Lannister) and Rose Leslie (Ygritte).

In a particular funny and poignant moment, Iwan Rheon (Ramsay Bolton) and Alfie Allen (Theon Greyjoy) embrace affectionately despite the fact Ramsay tortures Theon in the show.

Huge fans of Game of Thrones, Coldplay drummer had a guest cameo in the imfamous Red Wedding massacre in the third series.
